ADJUSTING OR CENTERING MECHANISM FOR TYPE-MACHINES..-

SPECIFIGA'IION forming part of Letters Patent No. 782,536, datedFebruary 14, 1905.

I Application filed July 11, 1904. Serial No. 216,163.

To all whom, it may concern:

Be it known that 1, JOHN SELLERS BANcRorr, of Philadelphia, in thecounty of- Philadelphia and State of Pennsy tain new and usefulingchines; and I do hereby lvania, have invented cer- Improvements in Adustor Centering Mechanisms for Type-Madeclare the following to be afull, clear, and exact descriptionof the same, reference being had tothe accompanying drawings, forming a part of this specifi: cation, andto the figures of reference marked thereon.

This invention relates to improvements in ad usting or centeringmechanisms for typecasting and other machines wherein the positioning ofa movable case, its carrier, the

element-such as the diemold-adjusting device, -or

other translatable memberis governed by perforations in arecord-stripand effected by a direct movement from one position to another after themanner disclosed in Patents Nos. 625,998, 674,37 6, and 749,149.

As heretofore constructed machines of the class mentioned have beenequipped with a primary gage in th e form of a plurality of stop-pinsserially arranged, a primary positioning mechanism in the form ofoppositelymovable jaws, of which latte-r one contacted with the selected,pin of the primary gage to determine the closed position of thejaws, a

secondary gage mov ed to position by the jaws of the primary positioningmechanism and there looked, a secondary positioning mechanism,includingopp ositely-movablejaws,con-

sive positions for and a control system intermediate the member to beadjusted,

the governing element and the primary gage for sepathe primary gage.

action the members of Each position or station in the series ofmovements provided for was represented by a separate pm in the primarygage, and each pin,

with the exception of the are represented by a last inthe series, wasprovided with a separate control mechanism or line'of communi- 5 cationwith a section 'of the record-strip, so that a perforation occurring inthat section would bring into action the corresponding pin of theprimary gage. To each positioning perforation was assigned a section ofthe rec- 5 5 ord-strip, and the width of the latter was dependent uponthe number of individual control elements of the primary gage. Thus thecentering mechanism for the die-case for positioning the latter by atwo-way movement of 6 fifteen degrees in each direction involved the useof twenty-eight movable gaging members or stop-pins, fourteen for eachdirection, with separate control devices and a governing perforation foreach member. This required that the record-strip should be of suchdimensions as to contain at least twenty-eight sections for receivingthe positioning signals or perforations and that thepunching-machineshould be equipped with a like number of punches forproducing the signals.

Now the principal ob ect of the present invention is to effect amaterial reduction in the dimensions of the record-strip andincidentally to simplify the construction of the primary gagmg andcontrol mechanisms by the employment of a signal and control systemwherein the various positions of adjustment instead of being representedby a correspond ing series of differently-located perforations limitednumber of such perforations employed singly and in various combinatlonsto represent successive or different positions.

To this end the invention consists in the con- 8 5 struction and use ofa composite gaging mechanism, including a plurality of gaging m'em-.

bers of difierent capacities arranged and adapted for separate orconjoint action, each gage member being provided with a control meansgoverned by a perforation in the record-strip,

so that any one or more of said gage memhere may be actuated and thegage thus set to correspond with the position represented by thedimension or capacity of any individual member or by the sum of thecapacities of any two or more members, all as hereinafter fullydescribed, the novel features being set forth in the appended claims.

In the accompanying drawings, illustrating tioning mechanism. Fig. 3 isa top plan view of the gaging mechanism. Fig. 4 is a trans verse andFig. 5 is avertical longitudinal sec tion through the gage.

Thesame numerals desigate like parts in the several figures.

The invention is illustrated as adapted to the die-case centering andmold -adjusting mechanisms of the type casting and composing machine ofPatent No. 625,998, wherein it supplants the primary gage in each of thetwo adjusting or positioning mechanisms. It will suffice for presentpurposes to designate certain of theprominent elements of said machine,reference being had to the patentmentioned for a more detaileddescription. These are the paper-feed mechanism, controlling themovements of the perforated record-strip l, and its application to theports 1", leading to the control devices, the die-case 2 and its carrier3, arranged for independent adjustment on intersecting lines andoperated upon by the two positioning mechanisms to center the matricesabove the mold by a direct movement from one to another, the secondarypositioning mechanisms (represented by jaws 4) for shifting the die-caseand its carrier and the mold-adjusting devices, the secondary gages 5for determiningthe closed position of jaws at, and the primarypositioning mechanisms (represented by the oppositely-movable jaws 6)for shifting the secondary gages and depositing them at any of a seriesof predetermined stations. The stations assigned to the secondary gagescorrespond to the different positions of adjustment permitted thediecase or other adjusted member, and it is the special function of theprimary gage to designate the successive positions of adjustmenteffected by the members of the centering on positioning system. The newcontrolling or gaging system is illustrated in a preferred form ofembodiment as applied to each of the two positioning systems, whereitsupplants the series of stop-pins and control devices of the priormachine; but as the mechanisms so applied are substantially duplicates adescription of one set will su'ffi'ce for both.

To thetop plane of the casting-machine .is detachably secured asupplemental frame 7 provided with guides or ways 8 to receive andsustain the oppositelyrmovable jaws of the primary positioningmechanism. One of said with a contact jaws is furnished surface9,-located to oneside of,

preferably latter,

or gaging below, the plane of movement of the opposite jaw and in linewith a fixed contact-surface or abutment 10, carried by frame 7. Thisfixed abutment, preferably in the form of a screw or equivalent meansfor initial adjustment, corresponds in position with the fixed stoppinof the prior primary gage and, like the serves to define one extreme ofthe series of-stations or positions of adjustment to which the system isadapted. In the example given the system corresponds with that of theprior patent-that is, it embraces a series of fifteen equally-spacedstations, of which the abutment represents the last or fifteenth andserves as a datum-line for locating the other stations.

Supported in position to be, interposed between the relatively movablegaging-surfaces 9 and 10 is what is herein termed a differentialpermutation-gagethat is, one comprising a plurality of individual gagesor interponents of relatively difl'erent dimensions or capacitiesadapted to be interposed separately or serially in combinations of twoor more between said gaging-surfaces to admeasure their relativepositions.- In the preferred form of embodiment herein illustrated thegaging members or interponents of this composite gaging mechanism arerepresented by four gage-blocks 11 of one, two, four, and eight unitscapacity, the unit in this case being the'interval between adjacentstations in the series. It is of course understood that the dimension ofthe unit and relative sizes of the individual gages may be varied tosuit the particular system employed and that the capacity of the gage asa whole can be increased or diminished by the addition or omission ofindividual gages; but as applied to the present system it will be foundthat with four differential gages of the dimensions given all of thestations designated by the fourteen movable stop-pinsof the priormachine can be accurately and positively gaged. Thus the fourteenthstation, one unit removed from the fixed abutment, can be located by theinterposition of the one-unit gage between the abutment and movable jaw6. The thirteenth station can be located by the interposition of thetwo-unit gage, the twelfth by the one and two unit gages in combination,the eleventh by the four-unit gage, the tenth by the one and four unitgages, the ninth by the two and four unit gages, the eighth by the one,two, and four unit gages, the seventh by the eightunit gage, the sixthby the one and eight unit gages, the fifth by the two and eight unitgages, the fourth by the one, two, and eight unit gages, the third bythe four and eight unit gages, the second by the one, four, and eightunit gages, and the first by the two, four, and eight unit gages. Thesignificance and advantages of such a system wherein gages of: differentdimensions are adapted for use singly and serially in combinations oftwo or- I jaw 6, carrying contact-surface 9, in order that it may bemoved into contact with the fixed abutment or an intermediate gage to.

measure the movement of said'jaw and arrest 1t 1n designated position,to whlch end said gages are carried on arms 12, disposed in dif-1 ferentplanes and each provided with a sleeve 13 or equivalent support engagingone of a series of parallel guides or rods 14. Each rod 14 is providedwith a limiting-stop 15 for positioning its gage when retracted, atwhich. time the several gages are supported in alme- 'ment and below theplane of movement of contact-surface 9 by restingupon the face of frame7. To effect and insure the return of the gages to initial positionafter having been elevated into alinement with the jaw and moved by thelatter toward the fixed abut: ment, the two, four, and eight unit gages'11 are each provided with a shoulder 16in a po-.

sition to be engaged by one of a series of shoulders 17 on a rod'18,attached to andcarried by the movable jaw 6. The shoulders 16 and 17 forthe respective gages are located in different planes, so that as the awadvances toward the fixed abutment the shoulderson' rod 18 will clearany of the gages that may happen to be elevated and upon the return ofthe jaw each shoulder 17 will engage and draw to initial position thecorresponding gage.

Each gage 11 is provided with control means whereby it can be moved intogaging positionthat is, in the present instance into alinement withmovable contact-surface 9 and the fixed abutment and with any other gageso moved into alinement. For this purpose a piston 19, provided witharetracting-spring 20 and working in a cylinder 21, is located beneatheach gage in position to elevate the latter into the planeofcontact-surface 9 when pressure is admitted to the cylinder, a shoulder22 on the piston-rod serving to limit the advance of the latter andprevent contact with the jaws. The first or one-unit gage 11 may beattached to and guided by its piston; but the others merely rest uponthe ends of their piston-rods, so that they are free to move thereonwhen engaged by contact-surface 9. The pistons as applied to thesemovable gages are preferablylocated beneath the ends thereon nearest thefixed abutment, in order that each may remain in contact with andsupport its gage when the latter is moved to an extreme position ineither direction, to which end the gages are disposed in sequence in;the

to cover all the required stations, but would be permitted a movement ofseven units, if

vused alone, andthus be carried beyond its 1 control-piston unlessadditional or other means were employed to'prevent such action.

Each cylinder 21 is connected, through a passage 23, with one of theinduction-ports of the paper-feed mechanism, through which i theiraction is governed by the perforations in the record-strip.

From the foregoing description it is apparent that the composite gagingmechanism, with its fixedvabutment or datum-line and separate gages ofdifierent dimensions adapted for separate and conjoint use in variouscombinations, is entirely competent to measure or designate each of thefifteen stations required for positioning the die-case or other movablepart in one direction and that but four control devices are required forsetting the gage for any position within its capacity, which means, asapplied tothe machine illustrated, that but eight induction-ports andcorresponding, perforations in the record-strip are required to compassthe thirty adjustments previously effected through the medium oftwenty-eight ports and perforations, thus reducing thearea of therecordstrip assigned to these adjustments to less than one-third thatrequired by the primary gages of the prior machine.

The new gaging system is admirably adapted for expansion to cover 'alarger range of stations or positions than is required in the machineillustrated as, for example, in the mold-dimensioning systemofapplication Serial No. 191,382the number of possible com-i binationsbeing greatly increased by the .addition of each gaging member with itssingle control means and governing perforations.

Not only does the improved gaging systemoperate to materially diminishthe size of the record-strip w-ithouta corresponding change inits-capacity; but it contributes to a simplification of ther.ecord-stripperforating mech-- anism by reducing the number ofpunchesrequired for forming the designating perforations orv signals.
